PASSWORD SECURITY FOR SERIAL REMOTE
COMMUNICATIONS
In order to provide security for remote access of the T300/T300M, a
LOGON
feature
can be enabled to require a password before the instrument will accept commands. This
is done by turning on the
SECURITY MODE
(Mode 4, Table 6-1). Once the
SECURITY MODE
is enabled, the following items apply.
•
A password is required before the port will respond or pass on commands.
•
If the port is inactive for one hour, it will automatically logoff, which can also be
achieved with the LOGOFF command.
•
Three unsuccessful attempts to log on with an incorrect password will cause
subsequent logins to be disabled for 1 hour, even if the correct password is used.
•
If not logged on, the only active command is the '?' request for the help screen.
•
The following messages will be returned at logon:
•
LOGON SUCCESSFUL - Correct password given
•
LOGON FAILED - Password not given or incorrect
•
LOGOFF SUCCESSFUL - Connection terminated successfully
To log on to the T300/T300M Analyzer with
SECURITY MODE
feature enabled,
type:
LOGON 940331
940331 is the default password. To change the default password, use the variable RS-
232_PASS issued as follows:
V RS-232_PASS=NNNNNN
Where N is any numeral between 0 and 9.
